PMA-545+ Description

Short technical summary and product information.

The Mini-Circuits PMA-545+ is a high-performance monolithic amplifier (MMIC) operating from 50 MHz to 6 GHz. It is engineered with E-PHEMT technology to provide an ultra-low noise figure of 0.8 dB at 1 GHz and a high IP3 of +36 dBm at 1 GHz, making it ideal for sensitive receiver front-end applications.

 

This amplifier delivers a typical gain of 20 dB and an output power of +20 dBm at 1 dB compression at 1 GHz. It operates on a single 3V supply with a nominal DC current of 80 mA and is internally matched to 50 Ohms, simplifying external circuit design. The PMA-545+ is housed in a compact 8-QFN (3x3mm) package with an exposed pad for improved thermal performance and is designed for surface mount applications.

 

Its broadband frequency coverage makes it suitable for various wireless communication bands, including Cellular, PCS, LTE, and WiMAX. The ruggedized design can handle input powers up to +20 dBm without an external limiter, and it maintains consistent output power over the full operating temperature range, suitable for remote applications like LNB driver stages.
